White-throated Oxylabes
Oxylabes madagascariensis
Mid-sized tetraka with a bold white throat and eye-stripe. Brown on the back, rufous on the underparts, and bright rufous on the cap. Madagascar endemic that is found in low- and middle-elevation eastern and northern rainforest. Skulking but restless understory bird that prefers dense tangles. Sometimes joins mixed flocks. Common vocalizations are a quick, thrush-like up-and-down series, and a low, accelerating rattle.

分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description and an illustration of the white-throated oxylabes in the third volume of his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name Le rossignol de Madagascar and the Latin name Luscinia madagascariensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1789 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae he included the white-throated oxylabes based on Brisson's description. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla madagascariensis. The white-throated oxylabes is now the only species placed in the genus Oxylabes that was introduced in 1870 by the English ornithologist Richard Bowdler Sharpe. The genus name is from Ancient Greek oxulabēs meaning "quick at seizing". The species is monotypic: no subspecies are recognised.<p>In 2013, genetic studies determined that the Bluntschli's vanga (also known as short-toed nuthatch-vanga), a species described in 1996 from two specimens collected in 1931, was actually this species. The specimens were both juveniles in a poorly known brown plumage.

Black-and-cinnamon Fantail
Rhipidura nigrocinnamomea
A fairly small, long-tailed bird of montane forest on Mindanao. Rufous above with darker wings, a tail frequently held cocked and fanned, pale orange underparts, a black hood, and a broad white eyebrow. Forages in the understory for insects and often joins mixed-species flocks. Bundok Flycatcher and Eyebrowed Thrush both have orange chest, a black head, and a white brow, but Black-and-cinnamon Fantail is larger than the flycatcher and smaller than the thrush, with a totally different shape and habits. Voice includes a sharp “gyuk!” or grating chatter.
Buffy-fronted Seedeater
Sporophila frontalis
Large finchlike bird with a strong bill with obviously curved mandibles. Males have a distinctive face pattern—a gray head with a broken pale eyebrow, and a prominent pale mustache and throat. Olive-brown above and gray below with two pale wingbars. Females have no facial marks and are olive-brown overall with two indistinct cinnamon wingbars. Found at the forest edge and in second growth where it is largely dependent on bamboo patches.
Puna Ibis
Plegadis ridgwayi
Rather stocky, all-dark ibis of wetlands and lakes in high Andes; also wanders to coastal lowlands, where can be locally numerous. Usually in small groups. Feeds by probing with its downcurved bill. Breeding adult has dark chestnut head and neck, and red face. Nonbreeding and immature have whitish streaking on head and neck, and duller face. In flight, feet project only a short distance beyond tail tip. Compare with more slender and long-legged White-faced Ibis, but no range overlap.
